Researchers Katherine McGowan and James Wren inside RAPTOR-A, one of
four robotic observatories in the RAPTOR system. The wide- and narrow-field
telescopes mounted on the platform above them can be aimed at any point
in the sky in less than 3 seconds. When RAPTOR's computers detect a
transient optical event in a wide-field image, they aim the narrow-field
telescope at the event to take a close-up movie of it.
